Non DHCPed WAN

I've got pfSense 2 working fine on a DHCPed RJ45 connection (in other words, connected to another router). That was a test or learning phase. Now I've got to connect it to a connection that isn't DHCPed. I know things such as;

virtual gateway ip

I have an address to give to the pfSense firewall (I have a /28 batch of addresses

I've half got it work - what I did was System –-> Routing and here I entered a gateway address (the gateway public addresses on the connection). Now I can get on, but;

It says that it is using the same gateway for the lan as the wan - that sounds wrong!

I have only been able to enter 1 address, but there are about 12 that I need, most as dedicated public addresses for various vLans

The worrying thing is that it is so slow. I was speed testing a down speed of around 18 Mb before I put the line into the pfSense router - now it is too slow to even pull up speedtest.net's page. Or any other.

Yep, have set up dns addresses correctly - now have the situation where if i try and ping google from a laptop connected to the pfSense box, it gets the correct address, but times out on the pings. I can get pfsense to run a ping itself from diagnostics and that works fine.

Sharedband is a bonding setup (in UK here) where you get multiple lines which go into a modem/router box. Each of these routers outputs to a sharedband box and the sharedband boxes all output to a normal switch - you then take a feed off of another port on the switch to give you your bonded broadband.
